[R-SIG-Finance] index creation

[BBands]

Hi All,

Is there are elegant way to create security indices in R? I am
specifically thinking of things like equal-weighted industry group or
market sector indexes. I can do it the brute force way, but I can't
help but suspecting that there is a nice index constructor or
something similar lying about in some package that I haven't noticed.

Best regards to all,
